Problems solved by technology

[0003] Traditional gravity relays are subject to cost considerations. Usually, the two driving electric coils are partially wound on the same iron core. This causes that when the main system board drives the relay, after the armature is picked up, the conductive 24V will pass through the iron core to reverse Backflow to the output port of the standby system, resulting in abnormal port status detection

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0026] The present invention adopts a delay output processing method, and when the execution command is received from the relay limit state to the allow state output, the output structure will be operated asynchronously, which can effectively avoid the abnormal detection during parallel drive, and provide a delay operation for the relay feasibility.

[0027] Using the drive asynchronous delay output processing method, when the system receives the suction command, whether the main system or the backup system first executes the command, it first drives the mechanical switch part of the ...

Abstract

The invention relates to an asynchronous delay processing method of a safe driving unit. The asynchronous delay processing method comprises the step of performing asynchronous operation on a mechanical switch portion and an electronic switch portion of an output structure when receiving an execution command for outputting equipment driven by the safe driving unit from a state to another state. Compared with the prior art, the asynchronous delay processing method has the advantages of having good security, and completely avoiding the possibility of false detection and the like when primary and standby ports are driven simultaneously.

Description

technical field [0001] The invention relates to the safety technology of a railway signal system, in particular to an asynchronous delay processing method of a safety drive unit. Background technique [0002] In the railway signal system, the wayside drive unit is used to execute the drive command of the interlocking machine, and the output 24V voltage is used to drive the gravity relay of the 6502 relay circuit. [0003] Traditional gravity relays are subject to cost considerations. Usually, the two driving electric coils are partially wound on the same iron core. This causes that when the main system board drives the relay, after the armature is picked up, the conductive 24V will pass through the iron core to reverse Backflow to the output port of the backup system, causing the port status detection to be abnormal. Contents of the invention [0004] The object of the present invention is to provide an asynchronous delay processing method for a safety drive unit in order...
